For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3
There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.
There should be 6 orange picks.
You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.
So in this one, we are DECREASING by 25%, so we say 25% of 820...
25% × 820 =
.25 × 820 = 205
Now since we are decreasing by 25%, we take our answer and subtract it from the original amount, 820.
820 - 205 = 615
820 decreased by 25% is
615.
